-6x=0-12=-12= -6/-12 =2 So, X=2

4y=9-5=4 = 4/4= 1 So, y=1

Answer:

x=2

y=1

Explanation:

-6x+12=0

take 12 to the other side &it becomes negated then equate

-6x=-12

the negatives cancel out each other and therefore the answer is positive

x=2

4y+5=9

take 5 over to the other side &it becomes negated

4y=9-5

4y=4

y=1
